April 25 - National Telephone Day


Happy National Telephone Day! On April 25, we observe this day of tintinnabulation. 
  
Around the world, there are 9.82 billion mobile phones. And while some predicted the landline to be obsolete by 2020, there are still about nine hundred and thirty-one million landlines around the world! 
  
Obtaining a Patent 

The correct answer to a trivia question like “Who invented the telephone?” is the name on the patent. In this case, the whole world knows the answer is Scottish-born American inventor, scientist, and engineer Alexander Graham Bell.  

Had his attorney been delayed by foul weather or poor planning, the answer may be a different name. 

On February 14, 1876, American patent attorney Marcellus Bailey, one of Bell’s attorneys, rushed into the U.S. Patent office in Boston to file the patent for what would be the telephone. 

He, along with American patent attorney Anthony Pollok, helped prepare Bell's patents for the telephone and related inventions. 
Later the same day, American electrical engineer Elisha Gray filed a patent caveat for a similar device. A caveat is an intent to file for a patent. 

There was also a third contender. Italian inventor and immigrant Antonio Meucci filed a caveat in November of 1871 for a talking telegraph but failed to renew the caveat due to hardships. 

Of course, Bell is the father of the telephone. After all it was his design that was first patented, however, he was not the first inventor to come up with the idea of a telephone

Meucci, began developing the design of a talking telegraph or telephone in 1849. 

He devised an electromagnetic telephone as a way of connecting his second-floor bedroom to his basement laboratory, and thus being able to communicate with his wife.  

Between 1856 and 1870, Meucci developed more than thirty different kinds of telephones on the basis of this prototype. 

However, because Bell submitted his record first, the patent office awarded Bell the patent on March 7, 1876. Gray contested this decision in court, but without success. 

Alexander Graham Bell 

Born March 3, 1847, in Edinburgh, Scotland, United Kingdom, Bell, years later, taught at a boys’ boarding school.  

The sounds of speech were an integral part of his life. His father developed a “Visible Speech” system for deaf students to communicate. 

Bell would later become a friend and benefactor of American deaf-blind author, political activist, and lecturer Helen Keller. 

Three days after the patent was approved, Bell spoke the first words by telephone to his assistant. “Mr.Watson, come here! I want to see you!” 

By May of that same year, Bell and his team stood prepared for a public demonstration. And there would be no better place than the grand stage of the 1876 World’s Fair in Philadelphia, Pennsylvania. 

On May 10, in a crowded Machinery Hall, a man’s voice was transmitted from a small horn and carried out through a speaker to the audience. 

One year later, the White House installed its first phone. The telephone revolution began! 

On July 9, 1877, Bell Telephone Company was founded, and they installed the first public telephone lines from Boston to Sommerville, Massachusetts the same year.   

By the end of the decade, nearly fifty thousand phones existed in the United States.  In May 1967, phone companies across the country installed the one-millionth telephone! 

HOW TO OBSERVE 

Celebrate by calling someone and telling them Happy National Telephone Day! Share your vintage telephone pictures on social media using #NationalTelephoneDay to show the different phones that have been used! 

Educators, visit the National Day Calendar® Classroom for lessons designed around National Telephone Day. 
HISTORY 

In May 1967, the one hundred millionth telephone line was installed in the United States!  

On May 11, governors and dignitaries for U.S. territories joined 38th U.S. President Lyndon B. Johnson on the largest conference call ever held up to that date. Each governor, dignitary, and the U.S, President were issued gold phones to commemorate the day.  

At the same time, a proclamation was issued declaring May 12th as National Telephone Day.  

There is no record of the day being observed again on that date. However, National Day Calendar continues to research the origins of this technology day.

April 25 - National DNA Day


Happy National DNA Day! On April 25, people across the nation recognize this day.  

On this day in 1953, American molecular biologist, geneticist and zoologist James Watson and British molecular biologist, biophysicist, and neuroscientist Francis Crick formally announced their discovery deoxyribonucleic acid (DNA) in a short letter published in the science journal, Nature 

Fast forward to 1990 when scientists from around the world came together to begin mapping the human genome. 

In the fields of molecular biology and genetics, a genome is the genetic material of an organism. It consists of DNA. 

The genome includes both the genes and the noncoding DNA, as well as mitochondrial DNA and chloroplast DNA. The study of the genome is called genomics. 

Known as The Human Genome Project, approximately two thousand scientists in six countries set to work mapping the nucleotides contained in human DNA.  

In the process, the project learned that humans share genes with other species. Some of the species the project mapped included yeast, mice and the fruit fly – all species commonly studied in science already. 

"The genome is our map of life." ~42nd U.S. President Bill Clinton 

“Don’t tell me what I know, Travis!” ~Gideon Grey 

On June 26, 2000, the first draft of the human genome was released. By April of 2003, the project released its finished human genome. The mapping of the human genome has transformed medicine and research.  

The ENCODE (Encyclopedia of DNA Elements) Project launched soon after the human genome was sequenced to further study and catalog data related to the human genome. Research including the study of different cancers and more advanced diagnostic tests may change medicine forever. 

HOW TO OBSERVE 

Students, teachers and the public are encouraged to learn more about genetics and genomics. Read books about DNA and its discovery or watch documentaries.

HISTORY 
  
In 2003, the U.S. Senate and the House of Representatives proclaimed April 25th as National DNA Day, as a one-time celebration.  

Each year after 2003, National DNA Day celebrations have been organized by the National Human Genome Research Institute

Since this time, several groups have also declared April 25 as International DNA Day and World DNA Day.
